Feb 24,2023 | David
Bone conduction earphone is becoming more and more popular among sports enthusiasts. Driven by them, more and more people are interested in this new type of headphones. To help you better understand them, here are some facts about this type of earphones.
1. Bone conduction earphones are new headphones developed using bone conduction technology, which transmits sound through bones;
2. They do not cover the ears, nor do they need to be inserted into the ears;
3. They will not damage the ears, they are the healthiest earphones for the ears. Because their sound transmission does not require the use of the eardrum, damage to the eardrum and auditory hair cells is minimal.
4. Bone conduction earphone is not noise-canceling headphones. They don’t sound as perfect as traditional noise-canceling headphones. But if you’re using them for normal music listening, their sound quality is perfectly fine.
5. Bone conduction is a mature technology, bone conduction earphone is a new application of this mature technology, and you can use it with confidence;
6. Bone conduction earphones are not headphones with external speakers. It relies on the vibration unit to generate mechanical vibrations, and the sound is transmitted to the inner ear to make people hear the sound.
7. Bone conduction earphones generally have better waterproof performance. Their sound generation and sound transmission methods make them not need to reserve holes in the fuselage, and the entire headphone can be integrated.
8. They will have a slight sound leakage problem. But some better products handle sound leakage better.
How do bone conduction earphone work？
To understand how bone conduction earphone work, let’s first understand how humans recognize the sound.
You may think that humans hear sounds with their eardrums, but this is not accurate. The sound we normally hear is vibrations in the air entering the ear and hitting the eardrum causing it to vibrate. Humans perceive the vibration of the eardrum through the cochlea located deep in the ear and transmit this information in the form of sound to the brain to perceive sound. In other words, humans perceive sound through the cochlea. From this perspective, humans hear sound through the cochlea.
Bone conduction earphone make good use of the above-mentioned mechanism of the cochlea to perceive sound. They apply vibration directly to the facial bones, and the facial bones transmit the vibrations to the cochlea, where the sound is perceived by the cochlea.
We can compare the difference between bone conduction and traditional sound transmission paths to understand more deeply how bone conduction earphone work.
Bone conduction path: sound wave,cranium,bone labyrinth,inner ear lymph,Spiral organ,auditory nerve,cerebral cortex auditory center.
Traditional sound transmission path (i.e. air conduction path): sound wave,auricle,external auditory canal,eardrum,auditory ossicles,vestibular window,internal and external lymphatics,spiral organs,auditory nerve,cerebral cortex auditory center.
We can see that the sound transmission process of bone conduction earphone does not need to pass through the eardrum, its sound transmission path is shorter, and it will not damage the eardrum.
They way they work bring a lot of benefits.
What are the advantages of bone conduction earphone?
First of all, because they use the principle of bone conduction to transmit sound instead of air conduction, most bone conduction earphone do not affect the acquisition of ambient sound by both ears when used. Therefore, it is very safe when you use it outdoors, and you will not ignore the possible dangers because you are immersed in the music when wearing it.
Secondly, because most of the them are close to the hard bone position (beside the ear), instead of directly blocking the ear canal like in-ear headphones, or clamping the soft tissue of the ear like clip-on headphones.After wearing bone conduction earphone for a long time,ear damage cause of Headphones is much less than in-ear headphones or clip-on headphones. For example, if you wear them for four hours, clip-on headphones may cause your ears to hurt unbearably, but even if you wear bone conduction earphones for a long time, you will basically feel nothing. Therefore, they are very comfortable to wear.
On top of that, common headphones can clog the ear canal, leading to the growth of a lot of bacteria that can lead to ear infections. Bone conduction earphone do not have these effects because they do not need to be worn in the ear, and they will not rub against the external auditory canal when worn. So they are more suitable for people with oily ears, otitis media, small ears, and some people with sensitive ears because they do not need to be inserted into the ears. They are also more suitable for people who need to wear headphones for a long time. Therefore, bone conduction earphones are very healthy.
Bone conduction earphone have relatively little hearing damage, because hearing damage generally occurs in the eardrum and inner ear, while bone conduction earphones directly bypass the eardrum to avoid eardrum damage. Moreover, the vibration waves of them are relatively moderate, and the impact on auditory hair cells will be less, so the damage to hearing caused by them is minimal. For these reasons, bone conduction headphones have become very popular these years.
Of course, bone conduction earphone is not perfect, and they have their drawbacks.
The first is that the sound quality is not as good as traditional headphones because of its wearing method. Due to its design characteristics, the anti-interference effect is not ideal in noisy environments such as shopping, taking the subway, and taking a car. Because it is transmitted to the ear ossicles through the skin and skull, so their degree of music reproduction is not as good as traditional in-ear headphones.
The second is that the phenomenon of sound leakage still needs to be overcome. If there is a common problem with bone conduction earphone, it is the problem of sound leakage. Although major manufacturers are trying to improve the sound leakage, judging from the actual status, sound leakage still exists in the headphones.
Although bluetooth bone conduction earphones also have some shortcomings, with the progress of technology, these two shortcomings have been greatly improved. Some technologically leading brands, such as Wissonly and Aftershokz, have made great progress in improving sound quality and reducing sound leakage. Next, I will introduce some good Bluetooth headphones.
